That schedule is really intense. I have to commend you by sticking to such a rigourous schedule. But I must say, you don't have to practice 5 - 7 hours a day! Stick to about an hour or 45 minutes per day and that should be enough. Too much practice will overwork your fingers and hand muscles, leading to injuries, especially now since you already have a broken wrist!
You have to take it easy. Your wrist will most likely heal, but once it does, I recommend not practicing more than 2 or 3 hours each time. A lot of guitar players tackle the instrument too hard and they get burnt out.
That's my suggestion.
